A method and apparatus for selecting packets from a plurality of packets containing one or more copies of data, the method and apparatus selecting packets such that a single copy of the data can be selected. The method using identifying information contained within the packets to select only packets which contain unselected data, and using a searchable means to maintain a memory of unselected packets. Packets are selected as they become selectable and no unnecessary delay or data loss is suffered if some of the packets suffer loss. The method is suitable for selecting packets on a receiving device which receives duplicate copies of data packets from physically diverse paths, for example, as used by the FIX protocol. The method both hardening data against loss and delay and enabling improvements in average delay and jitter when used on a receiving device to select packets.
